When Malik uses his "Eternal Serenade" Mystic Arte to finish off Spoiler:Lambda, the final boss of the main storyline, he will claim it to be the last time he uses said move.

However should the player later win any battle using this move in the "Lineage and Legacies" mode set after the main story, with the above criteria achieved, a special victory scene will play where Sophie points out that Malik stated he'd not use the move again. Malik will humourously lie and claim that he was referring to his other move "Eternally Sauteed."

The sword that Veigue Lungberg uses when fighting him at Riot Peak is Siegfried's "Requiem" sword from the Soul Calibur games, specifically the Player 1 variant. The Requiem sword that Veigue requests the player to find is the Player 2 variant.

During the events at Warrior's Roost's "Riot Peak" challenge, the player is assisted by a black robed guardian.

Upon completing the Riot Peak Normal class, the player will meet with and be challenged by the guardian, who reveals himself to be Veigue Lungberg, the main character of Tales of Rebirth. Upon defeating him, the player earns the Laevatein sword for Asbel. Veigue will also put in a Request for the player to find a sword named "Requiem" for him.

The player can challenge Veigue again any time they desire after winning or losing to him, although should the player challenge him after winning, they will have to fight him solo with the character they have chosen.

The player can also battle Amber Hearts from Tales of Hearts, and Reala from Tales of Destiny 2, within the bonus dungeon "Zhonecage." When beaten, they give out requests for certain weapons. Once these requests are fulfilled, Amber and Reala can fight alongside Veigue in the final battle of Riot Peak.

Special "Tales series" costumes are available as downloadable content for the game, each costume being based off of characters from different games in the series.
